How to use this document

Copy the template below into your quality system. Replace every <<FILL: ...>> placeholder with your company, system, and process specifics, then route it through your own document control, review, and approval. The filled specimen shows one worked example; adapt the numbers and scope to your operation and verify each cited regulation or standard against the current source before you rely on it.

This is a generic, originally worded starting point. It contains no confidential, proprietary, or employer material, it is drafted with AI assistance and reviewed, it is not legal or compliance advice, and adopting it does not by itself create or prove compliance. See the Disclaimer and Terms.

This is a ready-to-use periodic Continued Process Verification (CPV) trend summary report. It is not the annual product review (APR) or product quality review (PQR); it is a shorter, more frequent document that sits between the individual chart and the APR, so a reviewer can read what every monitored parameter did this period in one place, and so the APR has a single, dated document to cite instead of someone’s recollection of what last quarter’s charts looked like. Replace every <<FILL: ...>> placeholder with your own specifics and route it through your normal document control and review. A filled specimen follows. Verify each cited reference against the current source before you rely on it.

1. Purpose

This report summarizes, for the stated period, what every parameter monitored under the CPV plan referenced above showed, what signals fired, what was investigated, and what remains open, in one document that stands between an individual chart review and the annual product review or product quality review. It does not replace either; it gives both a common, dated statement of CPV status to draw from, so a periodic conclusion and the later APR/PQR conclusion for the same period are never found disagreeing after the fact.

3. Responsibilities

RoleResponsibility
CPV program ownerCompiles this report, confirms every parameter due for review this period was reviewed, holds the master schedule
Process owner / Manufacturing Sciences and TechnologyProvides the reviewer conclusion for each parameter under their ownership, confirms any assignable cause stated here matches the underlying investigation record
Statistician or trained designeeConfirms chart currency and the statistical basis stated for each parameter, including any limit still provisional
Quality AssuranceReviews and approves this report before it is cited in or attached to the APR/PQR

4. Prerequisites

Do not compile this report until the following are confirmed true for the period covered.

PrerequisiteConfirmed
Every parameter in the current traceability matrix has a chart or documented qualitative review current through the end of this period<<FILL: yes/no>>
Every signal logged in the CPV trend signal investigation and escalation log during this period has a status, open or closed, recorded against it<<FILL: yes/no>>
Any control limit recalculation completed during this period has its justification form on file<<FILL: yes/no>>
Any process change implemented during this period that plausibly affects a monitored parameter has been reviewed for its CPV impact<<FILL: yes/no>>

6. Parameter-by-parameter trend summary

ParameterChart / review typeData this periodSignal(s) this periodStatusReviewer conclusion
<<FILL>><<FILL: I-MR, Xbar-R/S, c/u/np/p, qualitative review, multivariate model>><<FILL: n, range>><<FILL: none, or rule and date>><<FILL: stable / signal under investigation / signal closed>><<FILL: a specific, non-boilerplate statement>>

Add one row per monitored parameter. A reviewer conclusion of “no concerns” with nothing else stated, repeated unchanged period after period, does not meet this report’s bar; state what the chart actually showed, even when the answer is that nothing changed.

7. Open items carried from the prior period

9. Program coverage check

QuestionAnswer
Does every parameter in the current traceability matrix appear in section 6<<FILL: yes/no; if no, state which and why>>
Was any parameter added to or removed from the monitored set this period, and is the matrix updated accordingly<<FILL>>
Does any parameter still rely on a provisional limit or qualitative review whose reconciliation trigger has now been met<<FILL>>

10. Overall conclusion

State a specific conclusion for the period, naming any open signal explicitly rather than issuing a general statement of control. A conclusion of “state of control maintained” sitting next to an unresolved open item in section 7 is the exact pattern this report exists to prevent.

Filled specimen

Extract for an example oligonucleotide drug substance program, third quarter of 2026. Company and numbers are illustrative.

FieldEntry
PeriodQ3 2026, 1 July to 30 September
Batches manufactured11, versus 9 the prior quarter
Parameters reviewed on schedule14 of 14
Signals fired2: one single-point assessment on full-length purity, closed; one formal investigation on a six-point upward trend on the same parameter, open at period end
Section 6 extract, full-length purityI-MR, n=11 this period, Rule 3 fired (six-point trend) mid-period, status “signal under investigation,” conclusion: “trend traced provisionally to a resin lot installed two cycles prior; investigation CAPA-2026-0143 open, root cause not yet confirmed; limits unchanged”
Section 10”State of control maintained with 1 open item under investigation (full-length purity trend, CAPA-2026-0143); no other parameter shows an unresolved signal”
Section 11”Flagged to the FY2026 APR author; the open investigation and its interim status, not yet a confirmed root cause, will be restated in the APR rather than assumed resolved by the APR’s later date”

The specimen shows what the report is built to do: it names the one open item specifically rather than issuing a blanket clean statement, and it hands that exact status forward to the APR author instead of leaving the APR to independently rediscover it from the raw chart.

Common inspection findings this report prevents

  • A CPV program with charts updated every batch but no document anyone reads between APR cycles, so a trend sits unnoticed for most of a year.
  • A periodic report’s reviewer conclusion copied forward unchanged from the prior period, discovered when a reviewer compares two consecutive reports side by side.
  • An open signal visible in a quarterly report that the APR, written months later, never mentions, because the two documents were never reconciled.
  • A parameter added to or dropped from the monitored set with no corresponding update to the traceability matrix or a stated reason here.

How to adapt this report

  1. Set your own reporting cadence in section 2; quarterly is common for a program with meaningful batch volume, but state the basis if a lower-volume program needs a longer interval.
  2. Build section 6 directly from the current traceability matrix so every parameter has a row; do not summarize only the parameters that happened to show something interesting this period.
  3. Treat section 7 as a running thread across reports, not a fresh list each time; a signal that closes should show its closure here, not simply disappear from the next report.
  4. Confirm section 10’s conclusion against section 7’s open items before approval, and confirm it again against the APR once that document is drafted.
